IMPROVEMENT |N GAS-BURN ERS.

Specification forming part of Letters Patent No. 204,278, dated May 28,1878; application filed May 14, 187e.

To all whom it may concern:

Be it known that I, WALTER ANDERSON, of Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Gas-Burners, of which the following is a specication:

Inconsiderate persons, especially those to whom gas-light is a novelty,are disposed to give full vent to the iiow, thereby entailing greatwaste of gas. In hotels, lodging-houses, and buildings rented inapartments for otices this is especially prominent.

The object of this vinvention is to remedy such evil by a device ofthe'simplest construction and most eective in its results, and which isnot liable to be accidentally displaced or forced out of position by thepressure of a full head of gas, however strong.

The gas-flow, as it passes through the burner to be burned, iscontrolled and regulated by the novel construction hereinafterdescribed.

Reference being had to the drawings, Figure 1 represents a verticalsectional view of a gas-burner embracing the improvements claimed; Fig.2, a side view, the burner-tip being removed; Fig. 3, views of theburner-r base and its regulator-cap; Fig. 4, a transverse view on theline w w, Fig. 2; Figs. 5, 6, and 7, views of modifications of myinvention.

In these drawings, a is the burner-base, which is provided with aninternal screwthread, whereby to fasten it to the pipe or bracket, as incommon use, and is formed or cast with a seat, b, and screw-thread c, topermit of the attachment of the burner-tip d; but the flow of gasthrough such burner-base to the burner-tip is interrupted, regulated, orcontrolled, and only permitted in substantially 'ascertained measurementby means of the following construction: On the burner-base, just abovethe screw-thread c, is a peripheral groove, e, the function of whichwill presently appear. Immediately above this groove is a series ofholes, 1 2 3 4 5 6-in the example shown, six-and these holes, 1, 2, 3,4, or 5, are covered by a check or regulator-cap, j', covering the openend of the burner-base, and which has a slot, g, capable, when the capis rotated, to leave open any one or all of said holes; but, of course,if all are left open the liow of gas will be uninterrupted. Thisregulator-cap f is held from coming off by an in- 'ner projection orteat, h, which extends into lfrom being accidentally displaced orgradually forced upward by the gas-pressure, so as to cover the escapeapertures or leave the base, and isthe feature of my improvement.

The manner of effecting the control of the flow of the illuminating-gasto the burner-tip, by the means described and shown, is as follows Theburner-tip being removed the check or regulator-cap is rotated or turnedon the axial line of the burner, so that its slot shall leave uncoveredone, two, three, or more of the holes. These holes are of a diametersuficient to permit the passage of one foot of gas an hour, so that, ifone hole be uncovered,

one foot of gas shall be burned, and if two be uncovered two feet ofgas, and so on. The

measured flow is, of course, 'in ratio to the pressure of gas. Thedesired ilow being obtainedby such adjustment, the burner-tip is screwedon.

In appearance, when the tip is screwed on, no person would perceive anyspecial difference between this device and the ordinary gas-burner.'Thus, unathorized interference would not be likely.

The check or regulator-cap may also be made to fit within the neck ofthe burner-base, the peripheral holes whereof are the same as in theexample shown and described; but an opening may be left in said capequal to the length of said series of holes, or the half of. p

its wall may be cut away. Thus, when the cap is rotated within the neckof the burnerbase, said opening or cut-away portion may be operated toleave one or more ofthe peripheral holes in the burner-base closed. Saidcap is provided with a surrounding groove to hold it 4in place. Thismodified construction is 'shown in Figs. 5, 6, and 7 of the drawings,wherein p represents the cap; q, the groovethereon, and r the opening orcut-away por` tion.

series of holes and peripheral groove, andthe burner-tip, substantiallyas described.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of the subscribing witnesses.

WALTER ANDERSON.
